Elon Musk's mom is the classy lady in Virgin America ads

Elon Musk may be famous for his inventions: PayPal, Tesla and SpaceX. But his mother, Maye Musk, has been making a name for herself as a working model.

An article about her son Kimbal Musk on Backchannel today revealed that mother Musk was part of Virgin America's fall campaign, which featured her elegantly holding a glass of champagne.

Maye Musk's modeling portfolio dates back to the 1960s when she was a finalist for Miss South Africa, according to her modeling website. Musk was also the cover model for the controversial New York magazine where she was the "pregnant old lady" in 2011.
